Our Next Energy Inc. (ONE), a battery technology startup from Michigan, claims its proof-of-concept battery powered an electric vehicle's range to nearly double that of Tesla's.
ONE's battery allowed the test vehicle to travel 752 miles without recharging. The EV completed the road test in December in Michigan and posted an average speed of 55 miles per hour.
ONE validated the results with a third party using a vehicle dynamometer, where the test vehicle achieved 882 miles at 55 miles per hour with the experimental battery.
According to ONE, the test vehicle was a Tesla Model S retrofitted with an experimental battery with 203.7 KWh and an energy density of 416 Wh/L.
Tesla's website says the EPA estimated range of its Model S is 396 miles.
The founder and CEO of ONE, Mujeeb Ijaz, said the company wanted to encourage electric vehicles by taking away range anxiety.
Ijaz added, "We are now focused on evolving this proof-of-concept battery into a new product called Gemini, which will enable long-distance trips on a single charge while improving cost and safety using sustainable materials."
ONE's experimental battery also exceeded the range of Mercedes' Vision EQXX. The German automaker said its four-door electric sedan prototype could go more than 600 miles per charge.
ONE is challenging the approach of adding more charging stations to combat range anxiety. The company stated today's electric vehicles lack the surplus energy to overcome factors such as high-speed driving, mountainous terrain, extreme weather or towing trailers in real-world conditions.
Ijaz said, "The ONE Gemini battery aims to eliminate range as a barrier to electric vehicle adoption by doubling the available energy on board in the same package space."
ONE plans to begin production of its first product, the Aries battery system, later this year, and to demonstrate a production prototype Gemini battery in 2023.
